Abstract

The article presents the deep structure of the poorly studied Uimon depression in Gorny Altai according to the data of transient electromagnetic sounding. The studies are relevant due to the high seismic hazard of the area, and are also in demand for prospecting and exploration of minerals predicted there. In order to construct geoelectrical models, data from several years of measurements were used, during which more than sixty soundings were performed. According to the electromagnetic data, the first deep well was drilled to a depth of 400 m in the central part of the depression, which uncovered a Neogene – Quaternary section. The well column is in good agreement with the geoelectrical models. At that stage, the interpretation was performed using computer systems within the framework of a horizontally layered model. The interpretation results are presented in the form of sections and three – dimensional visualizations that clearly reflect the structure of the depression.
